368 FXUS63 KILX 060756 AFDILX Area Forecast Discussion National Weather Service Lincoln IL 256 AM CDT Thu Jun 6 2024 .KEY MESSAGES... - A small (15-30% chance) opportunity for rain arrives this weekend as MCS activity passes to our south Saturday afternoon into Sunday morning. - Below normal temperatures will prevail through most of the forecast period. High temperatures stay in the mid to upper 70s through next Wednesday, before warming back up into the 80s for late next week. && .DISCUSSION... Issued at 256 AM CDT Thu Jun 6 2024 There is a secondary cold front entering central Illinois this morning. This will help dry us out the rest of the way, dropping dew points into the upper 40s to low 50s during the day. Behind the front, the pressure gradient has tightened and will deliver some breezier gradient winds to the CWA. The 00z HREF shows a 40-60% chance of wind gusts greater than 30 mph this evening after 5pm. Starting Friday, the synoptic pattern has an unseasonably deep upper- low anchored over Ontario and the Great Lakes and a strong high over the Desert Southwest into the Southern Plains taking a stronghold over central Illinois. Central Illinois will remain sandwiched between these two features embedded within deep-layer northwesterly flow. The forecast will remain mostly dry, but some MCS activity this weekend to our south/southwest could bring some rain up our way. There is a slight chance (15-30%) that the precipitation could be as far north as a Lincoln to Champaign line Saturday afternoon through Sunday morning. The temperatures will continue to be slightly below normal through the extended forecast. High temperatures stay in the mid to upper 70s through next Wednesday, before warming back up into the 80s to near 90 for late next week. Overnight lows will dip down into the 50s through Tuesday night, warming back into the 60s for late week. Copple && .AVIATION... (For the 06z TAFs through 06z Thursday Night) Issued at 1151 PM CDT Wed Jun 5 2024 A weak cold front will pass through central Illinois overnight. SW winds ahead of the front will gradually veer to the west then northwest. Precip is unlikely with frontal passage but some mid level clouds will accompany the front. NE winds will begin gusting to 20-25 kt starting mid to late Thursday morning and continue through around sunset. VFR conditions are expected through the period.
